Why the study?
Abnormalities in serum potassium levels have been associated with variable mortality risk among hospitalized patients with heart failure.
Do abnormal potassium levels (hypokalemia or hyperkalemia) affect inpatient mortality in hospitalized heart failure patients?
Do abnormal potassium levels (hypokalemia or hyperkalemia) affect inpatient mortality in hospitalized heart failure patients?
In hospitalized heart failure patients, hypokalemia is associated with nearly doubled inpatient mortality risk, whereas hyperkalemia is associated with a slightly decreased risk compared to normal potassium levels.
No takes yet. Share an insight, caveat, or question.
Hypokalemia was associated with higher inpatient mortality in heart failure; leaves open whether correction improves outcomes.
Basnet et al. (2019) studied this question.
